Created attachment 160365 [details] attachments requested by error message clang++ dumps core on attached code, which is likely not legitimate C++, as I was experimenting with syntax. compiled with: clang++ -o M.exe Multidim.cpp -L/usr/local/lib -std=c++0x In the source, removal of parenthesis around (&group), in AddGroup parameter list, and (&s), in array declaration in main makes problem go away.
A commit references this bug: Author: dim Date: Mon Jan 29 18:11:27 UTC 2018 New revision: 328555 URL: https://svnweb.freebsd.org/changeset/base/328555 Log: Pull in r217197 from upstream clang trunk (by Richard Smith): PR20844: If we fail to list-initialize a reference, map to the referenced type before retrying the initialization to produce diagnostics. Otherwise, we may fail to produce any diagnostics, and silently produce invalid AST in a -Asserts build. Also add a note to this codepath to make it more clear why we were trying to create a temporary. This should fix assertions when parsing some forms of incomplete list intializers. Direct commit to stable/9 and stable/10, since stable/11 and head already have this upstream fix.

This is not supported by gcc 4.2.1, which is still the default system compiler for some architectures. Direct commit to stable/9 and stable/10, since this does not apply to stable/11 and head.
